Initial phylogenetic comparisons based on a region of the DNA polymerase of seven herpes-like viruses found in sturgeons in North America and Europe indicated the presence of three distinct clades. A revised phylogenetic analysis of the same viruses, based on corrected DNA polymerase sequences and newly obtained sequence data from the putative ATP subunit of the terminase gene, indicate only two clades. These two clades correspond to the historical designations given to these herpes-like viruses from white sturgeon Acipenser transmontanus: white sturgeon herpesvirus type 1 (WSHV-1) and type 2 (WSHV-2). The identification of putative terminase gene sequences for all seven herpes-like viruses from sturgeons confirms their affinity with the family Herpesviridae (because this gene is unique to herpesviruses) and more distantly with T4-like bacteriophages. The two clades of sturgeon herpesviruses are therefore appropriately designated as Acipenserid herpesviruses 1 and 2, which correspond to the previous common names of white sturgeon herpesvirus types 1 and 2.

从鲟鱼分离的疱疹病毒的系统发育关系的修正

基于在北美和欧洲鲟鱼中发现的七种疱疹样病毒的 DNA 聚合酶区域的初步系统发育比较表明存在三个不同的进化枝。基于校正的 DNA 聚合酶序列和从终止酶基因的假定 ATP 亚基中新获得的序列数据，对相同病毒进行的系统发育分析表明只有两个进化枝。这两个进化枝对应于来自白鲟 Acipenser transmontanus 的这些疱疹样病毒的历史名称：白鲟疱疹病毒 1 型 (WSHV-1) 和 2 型 (WSHV-2)。对来自鲟鱼的所有七种疱疹样病毒的推定终止酶基因序列的鉴定证实了它们与疱疹病毒科的亲和性（因为该基因是疱疹病毒独有的），并且与 T4 样噬菌体的亲缘关系更远。因此，鲟鱼疱疹病毒的两个进化枝被恰当地命名为 Acipenserid 疱疹病毒 1 和 2，它们对应于白鲟疱疹病毒 1 型和 2 型以前的通用名称。
